To all whom it may concern.

Be it known that I, RICHARD H. BROWNE, a citizen of the United States of America, residing at Muskegon, in the county of Muskegon and State of Michigan, have invented certain new and useful Improvements in Knockdown Extensible Cabinets or Shelving; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in knock down extensible cabinetsor shelving, and its object is to provide a structure that can readily be taken apartand assembled, that can be extended longitudinally or transversely at pleasure, and-to provide the same with various new and useful features as hereinafter more fully described arid particularly pointed out in the claims reference being had to the accompanying drawings, in which Figure 1 is a perspective of a device embodying my invention; Fig. 2 an enlarged detail in vertical section of the reducing sections and parts adjacent thereto; Fig. 3 a detail of the same partially in front elevation and partially in longitudinal section; Fig. 4 the same as Fig. 2 with the reducing section omitted; Fig. 5 an enlarged detail in longitudinal section of the means for connecting the shelves and vertical members; and Fig. 6 a perspective detail of the coupling illustrating the coupling members attached to the shelves and their relation to the vertical members.

Like numbers refer to like parts in all of the figures.

1 represents the end panels of the device and 2 the intermediate panels. These panels 1 and 2 constitute the vertical members of the structure and by repeating the intermediate panels and the parts between the same and the end panels the device may be extended in length indefinitely.

3 represent reducing members whereby the depth from front to rear of the superposed section may be reduced by inserting the same between a deeper lower section and shallower upper section as illustrated.

4 are separate base members and 5 separate cap members secured in place in like manner to the shelves.

6 represent the shelves each end of which has a sheet metal coupling member 7 attached to the under side thereof, thence extending upward in a groove in the end of the shelf to near the middle thereof and thence extended outward horizontally opposite the middle of the shelf and having its outwardly projecting portion divided into two parts, one part being turned upward at right angles as at 10. and the other part being turned downward at right angles as at 11. This coupling member is of such proportion in the various parts that it will extend with its horizontal portion 9 between the vertical members and with the portions 10 and 11 extending upward and downward respectively into grooves l in the end panels and 2 in' the intermediate panels. The grooves 1 need not be as wide as the grooves 2 they receive but one coupling member while the grooves 2 in the intermediate panels receive two coupling members. 'So also the outer or end panels are cutaway only at the inner side ofthe groove to receive the coupling members and thus permit the outer surfaces to come. close to form a tight joint while the intermediate members are reduced at both sides of the grooves to receive the coupling members. By thiscon-' struction the shelves and the vertical members may be assembled as illustrated in Fig. 5 and will be effectually secured in place by means of these couplmg'members.

12 represents the lower stile of the front closure and l2 the upper stile of the same.

These are made to overlap and form tight joints as shown in Fig. 4. The reducing front member 3 of the section provided with an upwardly projecting portion 3 to engage the lower stile of the upper front closure. Each end of the reducing section is provided with a suitable-vertically narrow end member 13 to golbetween the endmembers of the other sections and is -also provided with a rear member 14. In the shelf 6 and in its upper and'lower sides and in the bottom of the member lt are grooves 6 to detachably receive the back panels 15 which also serve to hold all the parts in alinement. The reducing section is also provided with coupling members to fit between the other vertical members, the only modification being that the portion 7 is turned upwardly as at 7 instead of extending horizontally as in case of the coupling members for the shelves.

It will be noted that by the construction shown the device is readily reducedin depth from front to rear by using suitable reducas in most knock down structures of this character.

What I claim is 1. An ext ensibie cabinet or shelving, comprising sectional shelves, superposed vertical members having grooves in their adjacent ends, coupling plates projecting oppositely from between said members, and respectively attached to the adjacent ends .of two opposite shelves, each plate also having oppositely projecting vertical end portions adapt-ed to enter the grooves, said grooves in the intermediate vertical members being of sufficient width to receive two of said vertical end portions,- whereby a single series of vertical members support oppositely projecting shelves.

2. An extensible cabinet or shelving, comprising sectional shelves, superposed vertical members having grooves in their adjacent ends, and coupling plates secured to the under side of each shelf each plate having a portion extending upward opposite the end of the shelf, a portion extending outward between the vertical members and an end portion divided and turned vertically in opp osite directions to enter the grooves in the vertical members.

3. An extensible cabinet, comprising two or moresections of difierent depth from front torear, and a vertically shallow reducing section between said sections having a horizontal reducing portion adapted to connect the front closures of the sections arranged in 'diiferent vertical planes, andcoupling members connecting the reducing sections and the vertical sections.

4. An extensible cabinet, comprising sectional shelves, vertically disposed end sections and intermediate sections having grooves in their adjacent ends, a reducing section having shallow end members adapted to be interposed between two end sections of different widths from front to rear and having grooves corresponding to the grooves in the end sections and coupling plates on the shelves and reducing section, adapted .to extend between the end sections and engage the said grooves.

In testimony whereof I aflix my signature in presence of two witnesses.

RICHARD H. BROWNE.
